Description

Articulator for dental}

In particular, the present invention relates to a dental articulator, and more particularly, to a dental articulator capable of precisely adjusting an upper and lower rotational movement and a horizontal movement of a maxillary fixed bar about an axis and capable of joining and separating a tooth model firmly and easily on each of an upper and a lower fixed bar. , A base member to which a tooth model on the outside is coupled, and a fixing plate on which a base member is fixedly connected, is standardized, and a base member of various shapes can be coupled to each of the maxillary fixture and the mandible fixture without association of a fixture plate or an articulator. .

Generally, the teeth of the human body are formed into a substantially circular arc shape as a structure that can chew up various foods and the like as the upper and lower teeth are occluded through the movement of the temporomandibular joint.

Meanwhile, when a specific tooth is damaged, the above-mentioned occlusal action is caused to cause malfunction of the tooth. In this case, the predetermined restoration is inserted into the existing tooth to repair the damaged tooth.

At this time, in the process of manufacturing the prosthesis, an articulator is used to check the occlusal state.

As shown in Figs. 1 and 2, a conventional articulator includes an upper member 1 and a lower member 2, which are rotatably coupled to each other, and an upper tooth model and a lower tooth model, respectively, To check the occlusal state, and when the operation is completed, the gypsum is broken to separate the tooth model and the articulator from each other.

However, since the conventional articulator as described above is in a state in which the tooth model is coupled to the articulator through the gypsum, it is impossible to separate the teeth arbitrarily in the process of checking the occlusal state, and the gypsum is excessively used The gap between the upper and lower members of the articulator is excessively widened due to addition of gypsum for coupling with the articulator.

In addition, the use of gypsum results in a risk of damage to the tooth model and damage to the articulator due to impact, etc., in the work of removing the tooth model after completion of the preparation of the tooth model. In addition to causing environmental pollution due to disposal of the gypsum, The workability is lowered and the cost of the gypsum material cost is increased.

In addition, when the tooth model is coupled to the articulator through the gypsum, it is difficult to separate the tooth model and the articulator.

In addition, in the method of mechanically fixing using the upper and lower grippers, it is fixed by the fastening means. Therefore, in the process of repeatedly performing occlusion several times, the fastening force is weakened and the occlusion posture is changed.

As a background invention of the present invention to solve this problem, Korean Patent Registration No. 10-0601345, which is known as a dental articulating articulator having a dual ball, is known. This has the characteristic that the attitude of the desired occlusion position is finely adjusted in the three-dimensional space and the fixation force can be exerted firmly by the principle of the lever at the adjusted position. However, there are three fixing bolts, .
